Heath – Wikipedia

A heath (/ ˈ h iː θ /) is a shrubland habitat found mainly on free-draining infertile, acidic soils and characterised by open, low-growing woody vegetation. Moorland is generally related to high-ground heaths with—especially in Great Britain—a cooler and damper climate.. Heaths are widespread worldwide but are fast disappearing and considered a rare habitat in Europe.
